To ALL WHOM 1r MAvcoNcERN;

Be it kn/own that we, THOMAS WmLIAMsand JOSEPH J, Yarns, of the city, county, `and State of New York, have invented anew and'improved Heating-Apparatus; and we do hereby declare that the followingis a full,-., clear, and exact description thereof, which will enable others skilled'in the art to make' and use the same,'refer-v ence being had to -the accompanyiugdrawings, forming part of this specification, ir'mvhich- Figure 1- isa plan or top view of my improved heating-apparatus Figure 2 is an enlarged detail vertical section, taken through the end ota 'steam;pip'e,and showing the valvewhichis arranged therein.

Similar letters of reference indicate corresponding parts.

This inventonrelates to a devic'e for evaporating the liquors in whiskey-distilleries, and forother purposes' in which liqiiids are to he heated by blowing steam into them. l i i The invention is designed toovercome the diculh'es heretofore experienced, that when the steam was cut off, a vacuum was created in the steam-pipe, so that the material in the mash or other pan tlowed into thepipe andxclogged the same, therebycreating frequent annoyance and loss of time.

p To overcome'this diliicultyLI have arranged 'ai self-operating-,valve n each hole in the steam-pipe, so that the said hole will be closed instantly, as soon as the Asteam is\cut oif. I also, inV place of the ordinary worm, have arranged a stra chtmain steam-pipe, which passes .directly through the tub or pan, and from which small pipes-branched?, the ends of which are be'nt down and open, so that'the steam escapes'througli the openings in thesepip'es.l A valveis arranged inthe opening of the pipe, and prevents the charge from entering the same- It is not tobeunderstood'from thefabovethat these valves may not be applied to the openings in theordinarywo'rms, as 'theyiwould'do as good service there as on the small pipes.

The objectief the arrangement of pipes above referred to is, that the steam can, if the main pipe is opened, bev madeto pass through thesame withoutentering the'small pipes, thereby preventing too high pressure'of steam in thelarge pipe in case one of the smaller pipes bursts. i p p i, A represents a mash orother tub. B, the main horizontal steam-pipe passingthrough the tub, as is clearlyshown in g,1. Itis arranged a little above the bottom of the tub, and is secured inposition by means of locknuts a a'. Its end, b,is made fast to the tupply-pipe, while itsopposite end,c,'is or cau be closed bya cop or cock, d. C C are small pipes which branch off freni the pipe B', and'the ends of which areso arranged. that they are equallydstributed above the bottom of the pan, so that the steam that escapes from' their endswill be sweptcver the whole bottoni of the tub, and through the entire ma'ss of the liquid with whchfthe tub yis charged. The steam enters the pipe-B at h, and then passes through the pipes C and into the tub, as long as the cap d `is closed. As soon as that is opened,'the steam will rush through the pipe B, without entering thebranc'hes C,

until the supply i s cut oi' ortho cap again closed. I The ends'of the branch-pipes C are bent down, as is clearly shown in tig. 2, and into vthe same is screwed a short tube, Dhaving.u. bevelled lower edge, e', whichsforms the seat for a valve, E. The latter has a tapering body, so as to iit, the bevelled seat, and is provided with a stem, f, as shown.' The stem passes through al tube,g, which is held by arms,]z, in the eehtre of -the t-nbcl).

Between the-upper end of tube g and a pin, z'-, on top of stem f, is a spiral spring, F, which tends to close the;

valve as soon as the pressure of steam upon the same ceases. A shoulder,`j, is formedon the stem faboveV the tube g, and acts. as a stop, regulating thedownward motion' of the valve; site., when the shoulder strikes against the tube, the valve caunotbe forced dwniurthcr. The stem is screwed into the valve, and by that means the distancebetween the shoulder and upper end of. the` tube g ycan be increased or diminishedat will, tl1ereby permitting the valve to be more or` less. opened. 4At the lower edge of the valve is arranged an annular-horlzontal flange, lr, which breaks the inclined direction of the steam, into which the sameisf'forced by the taperd ing form of the valve. Thereby a4 greater area is swept by the steam from one pipe, and still the bottom of the` tub is touched, and may,`if required, be thereby washed.

Having thus described our invention, whatwe claim as new, and desire to secure by Letters Patent, is--g Y 1. Th'e heating-apparatus, `consisting of the main pipe B and branch-pipes (3, which are provided with'self closing valves E, substantially as and for the purpose herein shown and described. l

2. The valve when cnstruted as herein shown and descihed, so tht by lengtheningor shortening the stem the. amount ofsteamldischrged during al given 4timemay be increased or diminished at'will;

` 3. Proiding theMeaux-pipes in a. heatng-apparatuswvith self-c1osing'va1ves,' substantially as and for. the

' purpose herein shown and described.

1. The-annulanhoriz'ontal Hnge c, when arranged around the lower parte? vthe confal valve D, substantally as'hee'n shown and described.
